Document Type and Number:
Japanese Patent JP6646656
Kind Code:
B2
Abstract:
A method of adjusting video image data to reduce photosensitive epilepsy (“PSE”) triggers, the method including evaluating a sequence of video images to determine if the number of changes in brightness exceeding a predetermined threshold between contiguous images is greater than a predetermined value over a predetermined time or predetermined number of video images; and if the determined number exceeds the predetermined value then applying a correction procedure to the sequence of images. The correction procedure includes: for each image, applying a plurality of candidate brightness changes to the image and subsequently determining which of the applied changes result in the number of changes in brightness between contiguous images exceeding the predetermined threshold being reduced to below the predetermined value; and selecting the determined applied change having the smallest brightness change.
